Abstract

Polymerizable rubber-in-monomer solutions are made by contacting a conjugated diolefine with lithium or a hydrocarbyl lithium catalyst in a diluent non-polar medium boiling below 130 DEG C. to form a rubbery polymer, adding to the medium a monovinylidene aromatic hydrocarbon and, either before or after said addition, deactivating the reaction mixture, and stripping from the resulting mixture at least the greater part of those ingredients which boil below the boiling point of the monovinylidene aromatic hydrocarbon. When the monovinylidene aromatic hydrocarbon is added to the diolefine reaction mixture prior to its deactivation, block copolymerization takes place between the polydiolefin and a portion of the monovinylidene hydrocarbon. The products are rubber-in-monomer solutions which may be polymerized as such, or after the addition of natural of synthetic rubbers or other monomers, e.g. styrene and its derivatives and acrylic and methacrylic acids, esters, amides and nitriles. The polymerization of the rubber-in-monomer solutions may be effected by mass, suspension or mass-suspension techniques. The examples describe: (1) polymerizing butadiene in cyclohexane in the presence of n-butyllithium, deactivating the polymer with butanol, adding styrene, and removing solvent and unreacted butadiene by distillation to yield a rubber-in-monomer solution which is polymerized with the aid of di-tert.-butyl peroxide by a mass-suspension technique; (2) as in (1), but using a styrene-alpha-methylstyrene monomer mixture; (3) as in (1), but using an excess of butadiene as the reaction diluent in place of cyclohexane (4) as in (1), but deactivating the polymer after the addition of styrene, whereby a portion of the styrene forms a block polymer, and adding alpha-methylstyrene to the mixture after deactivation; (5) as in (1), but adding a mixture of polybutadiene, styrene and acrylonitrile to the rubber in monomer solution. The process of Example (1) may also be carried out in the presence of lithium metal, ethyl lithium, 2-ethylhexyl lithium, benzyl lithium and ethylene dilithium as catalysts. Specification 833,571 is referred to.
